Sandisk Q4 significantly beat expectations; multi-year contracts strengthen NAND demand and revenue visibility

Overview

This report reviews Sandisk's fourth-quarter results for the period ended June 2026 and its next-quarter guidance. The company's fourth-quarter revenue and margins both significantly exceeded market expectations and its own guidance, mainly driven by NAND price increases, shipment growth, and data-center demand. The company also expanded the scale of its multi-year NBM contracts, improving revenue and shipment visibility over the next several years. Although revenue is still expected to grow sequentially next quarter, the midpoint of revenue guidance was below consensus expectations, and the share price fell 6% after hours following the earnings call.

Core views

Sandisk's fourth-quarter fundamentals were strong, with estimated bit shipments up in the mid-teens percentage range QoQ and bit prices up about 30% QoQ. The data-center business more than doubled sequentially, showing that artificial intelligence and cloud storage demand remain important drivers of the NAND upcycle. After adding new multi-year contracts, the company expects NBM to cover at least half of bit shipments in FY27/6 and at least two-thirds in FY28/6, helping reduce price and demand volatility in the traditional storage cycle. Next-quarter revenue guidance below consensus creates short-term pressure, but the analysts believe its price increase being lower than Kioxia's mainly stems from different timing of price hikes and contract commencements, and does not deviate from their overall view of the NAND market.

Analysis framework

The report compares Sandisk's actual results with Bloomberg consensus as of August 5, 2026 and the company's prior guidance, and assesses operating momentum based on revenue, margins, bit shipments, bit prices, and end-market growth; it also analyzes the duration, coverage ratio, and minimum contractual revenue of NBM multi-year contracts, and compares them horizontally with price changes at Kioxia Holdings [285A].

• SANDISK CORP（US.SNDK）

  Primary research target

  Strengths

  Quarterly revenue and margins significantly exceeded expectations; data-center sales grew 103% QoQ; multi-year contracts expanded and improved future shipment coverage; minimum contractual revenue is sizable.

  Weaknesses

  Consumer business sales declined 32% QoQ; the midpoint of next-quarter revenue guidance was below consensus; the share price fell 6% after hours following the earnings release.

  Comparison

  The QoQ increase in bit prices implied by results and guidance was lower than Kioxia's, but the report believes this difference can be explained by different timing of price increases and multi-year contract commencements.

  Risks

  Reversal in NAND price and demand cycles, contract execution or customer purchases falling short of expectations, slowdown in data-center demand, continued weakness in the consumer business, and valuation volatility caused by high market expectations.

• Kioxia Holdings [285A]

  Comparable company in the NAND industry

  Strengths

  Nomura assigns a Buy rating, and its recent QoQ increase in bit prices was higher than Sandisk's.

  Weaknesses

  This report did not provide its full quarterly financial data, making a comprehensive profitability comparison impossible.

  Comparison

  Sandisk's implied price increase was lower, but Nomura believes this is consistent with differences in the timing of price increases and multi-year contract commencements, rather than abnormal performance.

  Risks

  Also faces NAND cyclical volatility, price changes, and uncertainty in end demand.

Impact & implications

The earnings beat and expansion of NBM contracts indicate that demand for high-performance storage and the NAND pricing environment remain strong, and long-term purchase commitments from data-center customers may improve Sandisk's revenue stability, capacity planning, and margin resilience. In the short term, next-quarter revenue guidance below consensus expectations and the after-hours share price decline reflect previously elevated market expectations. For the NAND supply chain, the difference in price increases between Sandisk and Kioxia is more likely due to the timing of contract and price-increase recognition rather than a clear divergence in industry supply-demand trends.

Risks

• The midpoint of FY27/6 Q1 sales guidance was below market consensus expectations, and actual demand may be weaker than investors had previously expected.
• Consumer business sales declined 32% QoQ, indicating that end-market recovery remains uneven.
• NAND prices are highly cyclical; if the supply-demand environment reverses, revenue and high margins may come under pressure.
• Actual revenue from NBM contracts still depends on contract execution, customer purchasing progress, and floor-price mechanisms, and long-term commitments may not fully translate into expected profits.
• Data-center sales are growing rapidly, and the business's sensitivity to large customers and related capital expenditure cycles may increase.
• The share price fell 6% after hours following the earnings release, indicating significant market volatility risk under high expectations.

What to watch

• Whether actual FY27/6 Q1 sales can reach or exceed the guidance midpoint of $10.55bn.
• Whether gross margin can remain around 84%, and whether price increases can offset changes in product mix and costs.
• Subsequent QoQ growth rates of bit shipments and bit prices.
• Progress toward NBM reaching at least half of bit shipment coverage in FY27/6.
• Customer onboarding for new contracts, the pace of revenue recognition, and execution of floor-price terms.
• The sustainability of data-center business growth and whether the consumer business can stop declining.
• Whether the difference in price changes between Sandisk and Kioxia converges as contract commencement timing aligns.
